Floating point literals provide values that can be used where you need a float or double instance. There are three kinds of floating point literal. The JLS syntax rules combine the two decimal forms into a single form. We treat them separately for ease of explanation.
There are distinct literal types for float and double literals, expressed using suffixes. The various forms use letters to express different things. These letters are case insensitive. The simplest form of floating point literal consists of one or more decimal digits and a decimal point.
The optional suffix allows you to specify that the literal is a float f or F or double d or D value. The default when no suffix is specified is double. The meaning of a decimal literal is the IEEE floating point number that is closest to the infinite precision mathematical Real number denoted by the decimal floating point form.
This conceptual value is converted to IEEE binary floating point representation using round to nearest. The precise semantics of decimal conversion are specified in the javadocs for Double. Scaled decimal forms consist of simple decimal with an exponent part introduced by an E or e , and followed by a signed integer. The exponent part is a short hand for multiplying the decimal form by a power of ten, as shown in the examples below.
There is also an optional suffix to distinguish float and double literals. Here are some examples:. The size of a literal is limited by the representation float or double. It is a compilation error if the scale factor results in a value that is too large or too small.
Starting with Java 6, it is possible to express floating point literals in hexadecimal. The hexadecimal form have an analogous syntax to the simple and scaled decimal forms with the following differences:. Advice: since hexadecimal floating-point forms are unfamiliar to most Java programmers, it is advisable to use them sparingly.
Starting with Java 7, underscores are permitted within the digit strings in all three forms of floating point literal.
This applies to the "exponent" parts as well. See Using underscores to improve readability. It is a compilation error if a floating point literal denotes a number that is too large or too small to represent in the selected representation; i. However, it is legal for a literal to represent a non-zero denormalized number. If you need to express them in source code, the recommended way is to use the constants defined by the java.

Simple decimal forms Scaled decimal forms Hexadecimal forms The JLS syntax rules combine the two decimal forms into a single form.
Simple decimal forms The simplest form of floating point literal consists of one or more decimal digits and a decimal point. For example 0. Scaled decimal forms Scaled decimal forms consist of simple decimal with an exponent part introduced by an E or e , and followed by a signed integer. Here are some examples: 1. Hexadecimal forms Starting with Java 6, it is possible to express floating point literals in hexadecimal. The hexadecimal form have an analogous syntax to the simple and scaled decimal forms with the following differences: Every hexadecimal floating point literal starts with a zero 0 and then an x or X.
The digits of the number but not the exponent part! The exponent is mandatory , and is introduced by the letter p or P instead of an e or E. The exponent represents a scaling factor that is a power of 2 instead of a power of Here are some examples: 0x0.
Underscores Starting with Java 7, underscores are permitted within the digit strings in all three forms of floating point literal. Special cases It is a compilation error if a floating point literal denotes a number that is too large or too small to represent in the selected representation; i.

They are represented directly in the code without any computation. Literals can be assigned to any primitive type variable. Example byte a = 68; char a = 'A'. The output is: pi = point1 = Point[x=3,y=4] myName = Thomas. point2 is null. In this small Java program, 65, 77, , , 3, 4, 5 and 12 are numeric literals whose values are the. Java String Literals; Java Literals. Java literals are fixed or constant values in a program's source code. You can use any primitive type value as a literal e.g. boolean int, char and float. However, string is not a primitive type in Java yet we can use strings as literals. Later in this article string literals are discussed. Java Integer Literals.
